MAGAZINE FOR FIRE-ARMS.

SPECIFICATION forming part of Letters Patent No. 315,645, dated April 14, 1885.

Y Application filed December 6, 1884. (No model.)

To @ZZ whom it may concern.-

Be it known that I, JOHN M. MARLIN, of New Haven, in the county of New Haven and State of Connecticut, have invented a new and useful Improvement in Magazine Fire-Arms, of which the following is a specification.

My invention relates to magazine fire-arms; and it consists in certain improvements in such arms for releasing the cartridges from the magazine and controlling their passage from the magazine to the carrier, substantially as hereinafter described and claimed.

In the drawings7 Figure l is a side view of the barrel, magazine, and part of the breechcarrier mechanism of a fire-arm, substantially as described in my application for Letters Patent filed in the United States Patent Office November l5, 1884, No. 147,994, the same being partly in section, and broken away to show the internal mechanism. Fig. 2 is a side view of the magazine detached from the arm, partially in section, and broken away to show its internal mechanism. Fig. 3 is a section of the arm through line B B of Fig. l. Fig. 4 is an end View of the magazine, and Fig. 5 is a transverse section through the rotary sleeve near its open end. Fig. 6 is a view of the muzzle end ofthe arm with the magazine locked in place. Fig. 7 is the same with the magazineunlocked. Fig. `8 is a front end view of the cartridgecarrier which transports the cartridges from the magazine to the bore of the barrel. Fig. 9 is a verticallongitudinal section of the same. Fig. l() is a view of a portion of the carrier and frame-work of the arm from the lower side. Fig. ll is a view of a portion of the magazine-case and magazine,showing thelocking mechanism of the latter.

A is the barrel of the arm. C is the magazine-case. D is the magazine,which is removable from the arm to enable it to be lled with cartridges. The magazine has in its closed end a spiral spring, d, which bears against the plunger cl2, and the latter in turn presses upon the cartridges and forces them into the carrier E.

In order to confine the spring d in a compressed position while the cartridges are being placed in the magazine before inserting it into its case, I employ the following mechanism: I attach a sliding rod, d', to one side of the magazine, having on one end of it the hook h, which projects into a longitudinal slot, s, cut through the side of the magazine-tube from the collar d* toward and almost to the open end of the magazine. The collar d has a slot through it, in which the rod d slides to and fro longitudinally of the magazine. At the head end of the magazine the sliding rod d is attached to a stud, di, which projects ont- 6o wardly to form a thumb-piece, and inwardly through a short slot, s', in the magazinetube, in which it moves longitudinally with the rod d. The rod d' and stud d5 are held toward the open end ofthe magazine by a spiral spring, d6. In the plunger d2, in a inortise of proper shape, is placed a latch, di, pivoted at (ZT, and having a spiral spring, d", to press its hook upward into the slot s. When the plunger is pressed toward the head end of the magazine, the latch d engages in the slots with the hook h of the rod d@ as shown in Fig. 2. This retains the plunger against the spring d, and holds the latter in a compressed position while the cartridges are being inserted into the magazine. Vhen the magazine is pressed into the magazine-case C, the projecting part of the stud d5 enters the transverse member of the L-shaped slot x, and, coming in contact with the lower side of the slot is pressed against the tension of the spring d.G up to the head c of the magazine. This draws the rod d and plunger d2 in the same direction and brings the beveled part of the latch d' against the end of the slot s, which compresses the latch in- 85 ward against the spring d and releases the hook of the latch fromthe hook 7L of the rod d', thus allowing the plunger to bear upon the cartridges and force them out of the magazine into the carrier as fast as they are taken up by the latter. The head c ofthe magazine is now in the position shown in Fig. 7, when the magazine is revolved in its case C, bringing the head of the magazine into the slot c', made transversely in the under side of the barrel, 95 and also bringing the projecting part oi' the stud d5 opposite the longitudinal member of the L-shaped slot m, when the stud d5, by the action oi the spring d, snaps into this longitudinal part of the L-shaped slot and locks roo the magazine in place, so that it is incapable of either a longitudinal or rotary movement in its case C.

In order to prevent the cartridges from escaping from the magazine until the latter is in place in its case, I provide a collar, b, which is placed around the magazine-tube near its open end, and has in its side a slot, b. rIhis collar is capable of rotating around the magazine-tube by means of a circumferential slot, b3, formed in the latter, into which the end of a screw, b, enters, which is threaded into the collar b. Another slot is cut through the magazine-tube on the opposite side from the screw b4, and a spring-stop, b2, has its free end introduced into this slot andv its other end made fast to the inside of the collar b, so that by the revolution of the collar around the magazinetube the free end of this stop b2 will enter into or be withdrawn from the inside of the magazine. A pin, b5, is secured into the magazine-case and projects inwardly in such a position that when the magazine is inserted into its case the pin will enter the slot b in the collar b, the collar b at this time being turned so that the free endof the stop b2 projects into the magazine. When the magazine is revolved to lock its head end in place, as before, described, the pin b5 holds the collar b stationary, and the magazine revolving in this collar withdraws the stop b2 from the bore of the magazine sufficiently to allowthe cartridgev to pass by it and escape therefrom.

The use of such magazines with sliding breech-carriers for conveying the cartridges to the bore of the barrel has been attended heretofore with the disadvantage that the varying lengths of the cartridges, although slight, caused the face of the sliding breechcarrier to jam the head of the cartridge in the magazine next to the carrier, or the face of the frame-work in which the carrier moved up and down was caused to jam the point of the bullet of the cartridge inthe carrier, if the cartridge in the carrier was shorter or longer than the exact distance from the stop in the carrier to its forward face,where it joined the magazine. To avoid this difficulty I have devised the following construction of parts: E is the carrier-block sliding vertically up and down, as described in my application above mentioned, and having the longitudinal chamber e, of proper size to receive the cartridges, a stop, c', and slot e2. Instead of making the front face of this carrier-block in the same plane, I form the part of it above a horizontal plane passing through the axis of the chamber e projecting forward beyond the lower part of its face.

I then place the stop e in such a position that the point end of the cartridge shall project toward the barrel to a distance half-way between the planes of the upper and lower parts of the face of the carrier, substantially as above described. It will be evident that when the carrier is raised the point of the ball of the cartridge in the chamber e cannot touch the frame and barrel or jam against them.

As, however, the next cartridge in the magazine would be forced back against the face of the carrier below the chamber e, and thus lap by the -point of the bullet in the chamber, and thus prevent the carrier from being returned downward before the cartridge in it was pushed from it into the barrel,which might cause great inconvenience, I provide a tongue, e3, upon the forward end of the carrier below the chamber e, having its upper end rounded or beveled next to that chamber. This tongue slides in a suitable groove, e4, in the frame-work, and travels upward with the carrier, and, coming against the head end of the cartridge in the magazine, forces it forward into the magazine and holds it there. When the carrier returns downward and brings opposite to the cartridge against which the tongue bears the chamber e, it slides into that chamber, and the next cartridge following is controlled in a similar manner by the tongue. The groove e, in which the tongue e3 slides above the level of the magazine, also serves to allow the point of the ball of the cartridge in the carrier to traverse upward more freely, while the frame part on each side of this groove prevents the head of the adjacent cartridge in the magazine from rising upward before it is' pushed forward into the magazine by the tongue e3.I It will be seen that by this arrangement of parts the head of the cartridge in the magazine, bearing against the tongue e3, is held forward by that tongue,in the downward movement of the carrier, until the point of the ball part of the cartridge in the carrier has passed behind the head of this cartridge in front of it, and therefore this tongue and groove enable the carrier to be moved up and down with a cartridge in it from the positionin which the chamber e is in line with the bore of the barrel as often as may be desired, without danger of jamming either the forward end of the cartridge in the carrier, or the head end of the cartridge,which is adjacent to the latter in the magazine.

Instead of astop, e', in the carrier, the length of the carrier may be madesuch that the cartridge init is stopped or held by the framework behind it in a similar position as if the stop were used; but I prefer to use the stop, because it may be placed at different points in the carrier to accommodate different lengths of cartridges. It will always be found that the depth of the groove e* will be sufficient to allow for the varying lengths of cartridges which enter the carrier, and allow them to be carried upward without jamming, when the cartridges are made with an ordinary degree of accuracy.
